The performance of soft-decision decoding relative to hard-decision decoding has been studied, when the transmitted symbols are contaminated with AWGN over the channel. the Frame error rates (FER) decreases logarithmically, due to reduced number of frames in
errors, and it is apparent that soft-decision decoding (SDD) outperformed hard-decision decoding (HDD) because the later produces higher FERs than the former. The code is an application viterbi decoding.
